They may not be using grub to boot or may have modified their grub setup to put something else first/default.

so wouldn't do a reboot after apt-get dist-upgrade do the same or am I not understanding the question?

They also might just want it to go faster (particularly if they have funny devices that take a long time to initialise during a normal boot).

No doubt there are other reasons I'm not thinking of right now.

way quicker to use this handy tool, and time is more precious than diamonds or gold.

also with multiple installs on a single disk, much better to reboot with the new kernel without updating grub, and only have grub-update ONCE after the last install on the disk has been upgraded (rather than having grub update after each of the multiple systems is upgraded. SLOW. UNNECESSARY. a WASTE.)

the slower the system, the faster that extra time rebooting adds up. try kexec se7en, you might like it.
